Answer:
Step-by-step explanation:
Add them up and thats your answer
Given the radius of the inscribed circle, the length of any side of the octagon (and any other polygon) is given by;
Side = 2r* tan (180/n) where r=radius and n=number of sides.
For octagon, n= 8 and radius is given by , r= 7/2 = 3.5 ft
Therefore,
Side = 2*3.5*tan (180/8) 2.8995 ft =2.9 ft.
The correct answer is A.
Answer:
<u>A. Vertex: (1, -8); x-intercepts: -1 and 3</u>
Step-by-step explanation:
The vertex is the point of the parabola. Basically, the part where the parabola 'scoops' up.
So the point where it scoops up is (1, -18)
The x-intercepts are the points where the line or shape touches the x-axis. The x-axis is the lines that goes from left to right.
The places where it touches the x-axis is -1 and 3
Answer:
Step-by-step explanation:
Are the sides consistent with the Pythagorean theorem?
37² + 54² ≟ 62²
1369 + 2916 = 4285 ≠ 62²
Not a right triangle.
Good evening Gloria
3t(t+2)-3t² for t=19
Well the first thing we need to do is to replace 19 everywhere we see T
So let's do it together
3(19)(19+2)-3(19)²
57(21)-3(361)
1197-1083
= 114
I hope that's help and if you have questions please let me know :)
Please give my answer a Thanks and stars ↓
